In this paper the design of a novel 5.3 GHz wide band input and output matched low noise amplifier (LNA) is presented. The LNA uses a conventional cascode architecture and is implemented in IBM SiGe5AM technology. Powered by a 2-V supply the LNA features 11.13dB of measured power gain and a 3 GHz bandwidth at 5.3 GHz. The LNA draws only 8 mA current from a 2 V supply. Input and output return losses of -12.6 dB and -9.16 dB have been achieved, respectively.
